I have a mac mini a1347 (Oct 2012 ) model. In the spec it says "64-bit enabled". What does 64-bit enabled mean?

it means you have a 64 bit mac, for example you have 8gb RAM, you will need a 64 bit OS for your RAM to work properly, unlike 32 bit where that only supports 4gb RAM and lower. so i have to say that you have a good computer to be 64 bit.

    Maximim supported RAM: Ubuntu 32-bit - 4GB RAM, Ubuntu 32-bit + PAE (Physical Address Extension) - 64GB RAM, PAE is now the standard for 32-bit Ubuntu, so there is no need for enabling it. – karel Dec 07 '14 at 05:58
